Feeding fish

Intensification of pond culture includes a complex of measures aimed at improving fish productivity of ponds. These include clearing vodopodayuschih and drainage systems, removal from the ponds rigid vegetation, fertilizing the bed of the pond and sowing his crops, feeding fish, etc. the Greatest effect is achieved by feeding fish. Where the feeding is practiced, used multiple (two, three – five times) the landing of fish, fish productivity of reservoirs is increased 5-10 times.

For feeding fish more suitable drain, not overgrown, well reclaimed ponds. Should not be fed to fish in ponds where the water temperature is not heated above 15-16°, and with a large number of trash fish that eat the feed.

Feeding fish spend in the feeding tables or feeding sites, which have not sedimented areas with a depth of 60-70 cm, well lit by the sun. The amount of feed tables, feed or places is determined on the basis of one space for 200 carp.

Feed the square tables are made of tight-fitting plates of thickness 10 mm. the size of the table 1X1,5 m. At the edges of the nail rim with a height of 10 cm. the Trough is fixed by stakes with the bitches on the end to keep them from floating up, or other way.

For feeding carp use both plant and animal food. From plant Carmouche are peas, vetch, lupine, wheat, barley, oats, mill waste, various oil cakes, residues of alcohol, yeast, sugar, starch manufacture, of the animals – the remains of the meat and fish industry and some others. The nutritional value of these forages is characterized by different feed coefficients. Fodder coefficient in fish farming refers to the number showing the amount of feed expressed in kg. must be eaten by fish to produce 1 kg of her weight gain. For example, the feed conversion ratio of flax meal 4; this means that to produce 1 kg gain meat carp have to eat 4 kg of linseed cake. Continue reading

Gefilte fish

1 kg fish fillet (skinless and boned) — 1/2 loaf of wheat bread, 1 Cup milk or water (for soaking bread), 1 onions, 2 eggs, 2 cloves of garlic, 1 carrot, 1 beet, 1/2 parsley root, 1-2 Bay leaf, 3-4 peas of fragrant pepper, salt, ground black pepper.

Suitable for stuffing any meaty fish, not too oily, hard and without small intermuscular bones, white flesh, without a sharp specific smell and low fat fish fillet industrial production, better without dark skin.

From ocean fish for stuffing the preferred Grenadier, sea burbot and perch, fish-captain, blue whiting, saithe, cod, hake, Pollack. The meat of hake and Alaska Pollack is sometimes dry, kroshlivym, and the stuffing of them is badly molded. In this case, they should combine it with sea bass, cod or other fish, with more viscous pulp — like fish are taking 30-50 % of the weight of Alaska Pollock, hake. Continue reading

Innovative technologies for processing of pond fish

The main direction of realization of innovative policy in the Voronezh region is the organization of innovative industries based on resources available in our region. One such project is the integrated processing of freshwater fish found in a local freshwater pond aquaculture. At the moment in Voronezh works “Systems of the quality of life”, abbreviated as “SAY”, which is engaged in production of natural products using innovative technologies.

The project initiated by the UK “Sberinvest” managing the closed mutual investment Fund “Regional venture Fund of investments into small enterprises in scientifically-technical sphere of the Voronezh region” and supported by “Agency on innovations and development”.

Total investment in the project amounted to more than 23 million rubles. Continue reading
